[0033] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0034] The following is for reference. Figures 1-5 The present application describes a housing 100 for a heating, ventilation, and air conditioning (HVAC) system according to an embodiment of the present application. The housing 100 serves as a mounting carrier for multiple devices (such as compressors, fans, heat exchangers, etc.) in the HVAC system, thereby requiring the housing 100 to have good protective effects to prevent the HVAC system from malfunctioning due to external environmental influences during operation.

[0035] Among them, HVAC equipment can be constructed as rooftop units. Rooftop units are integrated indoor and outdoor units, featuring a compact structure that can be directly installed on the roof to save floor space. The indoor unit of the rooftop unit has high static pressure suction. In severe weather conditions (such as rain), water and other contaminants located outside the rooftop unit may be drawn into the unit through gaps between panels and between the panels and the chassis, potentially causing dripping problems indoors.

[0036] According to an embodiment of this application, the housing 100 includes: a panel assembly 1, a chassis body 2, and an inner chassis assembly 3.

[0037] Combination Figure 2 and Figure 3 As shown, the chassis body 2 has an upwardly protruding step 21, and the outer wall 211 of the step 21 is disposed opposite to and connected to the panel assembly 1 in the inward and outward directions, thereby connecting the panel assembly 1 to the outer wall 211 of the step 21, so that the panel assembly 1 can cover the outside of the step 21, thereby improving the protective effect at the joint between the panel assembly 1 and the chassis body 2.

[0038] It is understood that the panel assembly 1 is arranged vertically, and the lower end of the panel assembly 1 covers the outside of the step portion 21, so that the panel assembly 1 can cover the outer wall 211 of the step portion 21. The panel assembly 1 can be connected and cooperated with the outer wall 211 of the step portion 21, so that the panel assembly 1 can fit against the outer wall 211 of the step portion 21. The panel assembly 1 and the step portion 21 fit tightly, thereby preventing contaminants outside the housing 100 from entering the housing 100 through the gap between the panel and the chassis.

[0039] Furthermore, the inner chassis assembly 3 is installed on the step surface 212 of the step portion 21, and the inner chassis assembly 3 is located inside the panel assembly 1. A first sealing element 41 is provided between the inner chassis assembly 3 and the panel assembly 1. The first sealing element 41 can form a sealing protection between the inner chassis assembly 3 and the panel assembly 1, thereby improving the sealing protection effect between the inner chassis assembly 3 and the panel.

[0040] The stepped surface 212 is the upper surface of the stepped portion 21. The stepped surface 212 can support the inner chassis assembly 3, so that the inner chassis assembly 3 is positioned above the stepped portion 21. The term "inner" refers to the space of the housing 100 used to house equipment such as compressors, fans, and heat exchangers, while "outer" refers to the side of the housing 100 that is close to the external environment.

[0041] Reference Figure 2 and Figure 3 As shown, the inner chassis assembly 3 is mounted on the chassis body 2, and the inner chassis assembly 3 is used to install and support the HVAC equipment on the indoor unit side, such as fans, heat exchangers, etc. The panel assembly 1 can cover the outside of the inner chassis assembly 3, and a first sealing element 41 is provided between the inner chassis assembly 3 and the panel assembly 1. The first sealing element 41 can form a seal between the inner chassis assembly 3 and the panel assembly 1 to prevent contaminants from being sucked into the space within the housing 100 for accommodating fans and other equipment through the gap between the panel assembly 1 and the inner chassis assembly 3 by high static pressure suction, thus helping to improve the sealing and protection effect of the HVAC equipment.

[0042] It is understood that the chassis body 2 serves as the mounting carrier for the inner chassis assembly 3, which is positioned above the step portion 21. This allows the inner chassis assembly 3 to be positioned opposite the panel assembly 1 in the inward and outward directions. The sealing structure formed by the first sealing member 41 between the inner chassis assembly 3 and the panel is located above the step surface 212. In other words, the sealing structure formed by the first sealing member 41 is located further inward of the mating position between the panel assembly 1 and the outer wall 211 of the step portion 21, thereby further enhancing the sealing and protective effect at the mating point between the panel assembly 1 and the inner chassis assembly 3 and preventing contaminants from entering through the gap between the panel assembly 1 and the inner chassis assembly 3.

[0043] According to the embodiments of this application, the housing 100 for HVAC equipment has a stepped portion 21 formed on the chassis body 2 that connects and cooperates with the panel assembly 1. The panel assembly 1 is connected and cooperates with the outer wall 211 of the stepped portion 21, which can improve the protective effect between the panel assembly 1 and the stepped portion 21. The inner chassis assembly 3 is installed on the stepped portion 21, and the inner chassis assembly 3 and the panel assembly 1 are sealed and protected by a first sealing member 41, which can further improve the sealing and protective effect between the panel assembly 1 and the inner chassis assembly 3, and reduce the risk of external contaminants entering the indoor unit side through the gap between the panel and the chassis body 2.

[0044] Combination Figure 2 and Figure 3 As shown, in some embodiments of this application, the inner chassis assembly 3 includes an inner chassis 31 and an inner chassis cover 32. The inner chassis 31 is mounted on the chassis body 2 and has an upwardly open receiving groove 311. The inner chassis cover 32 covers the inner chassis 31 and is located on the open side of the receiving groove 311, so as to shield the receiving groove 311 by the inner chassis cover 32, so that the inner chassis cover 32 can form a support structure above the receiving groove 311.

[0045] Furthermore, a sealing flange 321 is formed on the inner chassis cover plate 32. The sealing flange 321 and the panel assembly 1 are arranged opposite to each other in the inward and outward directions. The first sealing member 41 can form a seal between the sealing flange 321 and the panel assembly 1 to prevent contaminants from passing through the gap between the inner chassis cover plate 32 and the panel assembly 1, thereby improving the sealing and protection effect between the inner chassis assembly 3 and the panel assembly 1.

[0046] Reference Figure 2 and Figure 3 As shown, the inner chassis 31 is connected and fitted with the inner chassis cover 32, and the inner chassis cover 32 is used to support the installation of the device on the inner side of the unit. The end of the inner chassis cover 32 near the panel assembly 1 forms a sealing flange 321, so as to improve the structural strength at the edge of the inner chassis cover 32 through the flange structure. Moreover, the sealing flange 321 can be set to increase the corresponding area of ​​the inner chassis cover 32 and the panel assembly 1 in the inner and outer directions, so as to facilitate the inner chassis cover 32 to fit with the first seal 41 through the sealing flange 321.

[0047] It is understood that at least part of the first seal 41 can be clamped between the sealing flange 321 and the inner wall of the panel assembly 1, so that the first seal 41 is clamped by the sealing flange 321 and the panel assembly 1 to achieve a seal.

[0048] Combination Figure 2 and Figure 3As shown, in a further embodiment of this application, the sealing flange 321 is bent toward the step surface 212 of the step portion 21, and the end of the sealing flange 321 is in clearance fit with the step surface 212 of the step portion 21.

[0049] Reference Figure 3 The inner chassis assembly 3 is positioned above the step portion 21, and the inner chassis cover 32 covers the inner chassis 31. In other words, the inner chassis cover 32 is positioned above the step surface 212. When the sealing flange 321 on the inner chassis cover 32 is bent towards the step portion 21, the contact area between the sealing flange 321 and the first sealing element 41 is ensured. Furthermore, the sealing flange 321 can be positioned near the step surface 212, ensuring that the sealing and protective structure formed by the first sealing element 41 is close to the step surface 212.

[0050] The inner wall of the panel assembly 1 is planar. When the panel assembly 1 is connected to the outer wall 211 of the step portion 21, the inner wall of the panel assembly 1 is fitted to the outer wall 211 of the step portion 21. By bending the sealing flange 321 downward (towards the step surface 212), the sealing flange 321 can avoid occupying the upper space of the inner chassis assembly 3, so that the sealing flange 321 can avoid the heat insulation component 13 (such as fiberglass wool) arranged on the inner wall of the panel assembly 1, thereby ensuring the heat insulation protection effect of the area above the inner chassis assembly 3.

[0051] Understandably, by fitting the sealing flange 321 with the step surface 212 with a clearance, a gap of a certain size (e.g., 1mm, 2mm, etc.) can be reserved between the lower end of the sealing flange 321 (i.e., the end adjacent to the step surface 212) and the step surface 212, thereby further improving the sealing and protection effect at the sealing fit between the sealing flange 321 and the panel assembly 1. In other words, even if water from outside the housing 100 is drawn into the step surface 212 in the step portion 21 through the gap between the panel assembly 1 and the outer wall, the water volume in the upper part of the step portion 21 needs to reach a certain value (i.e., the water level reaches the lower end of the sealing flange 321) before there is a risk of water being further drawn into the gap between the sealing flange 321 and the panel assembly 1. This increases the difficulty of water entering the interior side and improves the sealing and protection effect between the inner chassis cover 32 and the panel assembly 1.

[0052] In some embodiments of this application, a first sealing member 41 is disposed on the inner wall surface of the panel assembly 1 to facilitate the engagement of the inner chassis assembly 3 with the first sealing member 41. It is understood that during the assembly of the housing 100, the inner chassis assembly 3 can be first installed on the chassis body 2, and then the panel assembly 1 can be fastened onto the chassis body 2 to connect and fix the panel assembly 1 to the chassis body 2. During the fastening and installation process of the panel assembly 1 and the chassis body 2, the first sealing member 41 located on the inner wall surface of the panel assembly 1 can abut against the sealing flange 321 to form a seal between the panel assembly 1 and the sealing flange 321.

[0053] In some embodiments of this application, the first sealing element 41 is constructed as a sealing sponge, which is attached to the inner wall surface of the panel assembly 1. The attachment and mating assembly method is simple, which can reduce the difficulty of connecting and mating the first sealing element 41 and the panel assembly 1 while ensuring the reliability of the connection, and also makes it easy to set the thickness of the sealing sponge.

[0054] It is understandable that the sealing sponge is sandwiched between the sealing flange 321 and the panel assembly 1. The thickness of the sealing sponge when it is not compressed should be greater than the gap size between the sealing flange 321 and the panel assembly 1 in the inner and outer directions, so as to ensure the clamping and deformation effect of the sealing flange 321 and the panel assembly 1 on the sealing sponge, so that the sealing sponge can be deformed by the sealing flange 321.

[0055] In some embodiments of this application, in the vertical projection of the inner wall surface of the panel assembly 1, the projection of the sealing flange 321 falls within the projection range of the first seal 41, thereby ensuring that the sealing flange 321 and the first seal 41 are fully aligned and that the sealing flange 321 presses against the first seal 41.

[0056] It should be noted that the aforementioned "vertical" direction refers to the direction in which the sealing flange 321 and the first sealing member 41 press against each other, which can also be understood as the thickness direction of the panel assembly 1. When the projection of the sealing flange 321 falls within the projection range of the first sealing member 41, the surface of the sealing flange 321 opposite to the panel assembly 1 can be completely pressed against the first sealing member 41, thereby sealing and protecting the gap between the sealing flange 321 and the panel assembly 1 through the first sealing member 41, and the sealing and protection effect is good.

[0057] like Figure 3 As shown, in some embodiments of this application, the sealing flange 321 and the inner chassis 31 are opposite to each other and spaced apart in the inward and outward directions, so that space can be reserved between the sealing flange 321 and the panel assembly 1 for arranging the first sealing member 41.

[0058] Combination Figure 2 and Figure 3As shown, in some embodiments of this application, the inner chassis 31 is provided with a connecting flange 312 at the open end of the accommodating cavity. The connecting flange 312 is bent toward the side away from the accommodating groove 311, and the connecting flange 312 is disposed opposite to and connected to the bottom surface of the inner chassis cover plate 32 (i.e., the lower surface of the inner chassis cover plate 32), so that the inner chassis 31 can be connected and fixed to the inner chassis cover plate 32 through the connecting flange 312.

[0059] Reference Figure 3 As shown, the connecting flange 312 is attached to the bottom surface of the inner chassis cover plate 32 and connected to form a partial double-layer plate structure in the inner chassis assembly 3. This helps to improve the structural strength at the joint between the inner chassis cover plate 32 and the inner chassis 31, and facilitates the connection between the inner chassis 31 and the inner chassis cover plate 32.

[0060] It is understood that the connecting flange 312 can be connected and fixed to the inner chassis cover plate 32 by a connector (such as a screw), which is simple and has high reliability. Furthermore, in the embodiment of this application, the inner chassis assembly 3, by bending the connecting flange 312 away from the opening of the receiving groove 311, can set the connection position of the connector in a position that avoids the components (such as fiberglass wool) arranged in the receiving groove 311, thus ensuring the sealing effect of the receiving cavity formed by the inner chassis cover plate 32 and the inner chassis 31.

[0061] like Figure 3 As shown, in some embodiments of this application, the connecting flange 312 extends toward the sealing flange 321, and the end of the connecting flange 312 is spaced apart from the sealing flange 321, so as to ensure the correspondence between the connecting flange 312 and the inner chassis cover plate 32 while avoiding interference between the connecting flange 312 and the sealing flange 321.

[0062] Combination Figure 2 and Figure 3 As shown, the inner chassis cover plate 32 is installed on the inner chassis 31 to cover the open end of the receiving groove 311 on the inner chassis 31. By setting the end of the connecting flange 312 and the sealing flange 321 at intervals, the size of the inner chassis 31 is slightly smaller than the coverage area of ​​the inner chassis cover plate 32, which facilitates the fastening and engagement of the inner chassis cover plate 32 and the inner chassis 31.

[0063] Combination Figure 2 and Figure 3 As shown, in some embodiments of this application, the inner chassis cover 32 and the inner chassis 31 enclose a receiving cavity, and an insulation layer is provided in the receiving cavity. The insulation layer has the effect of isolating heat transfer, so as to form a heat insulation and protection structure at the bottom of the inner unit side, reducing the influence of the external environment of the casing 100 on the bottom of the inner unit side.

[0064] The "insulation layer" can be made of fiberglass wool (i.e., glass fiber cotton). Fiberglass wool has good heat insulation and heat insulation effects, which can reduce the influence of the ambient temperature outside the casing 100 on the indoor unit side and ensure the temperature control effect of the indoor unit side.

[0065] Reference Figure 3 As shown, the inner wall of the panel assembly 1 is provided with a heat insulation component 13, which also has the same heat insulation function. It can form a heat insulation layer at the panel assembly 1 to reduce the influence of the external temperature of the housing 100 on the indoor unit side of the panel assembly 1.

[0066] It is understandable that in the housing 100, the installation space on the indoor unit side is enclosed and defined by components such as the inner chassis assembly 3, the panel assembly 1, and the middle partition. By setting up protective components with heat insulation function such as heat insulation component 13 and heat insulation layer, the heat insulation protection effect on the indoor unit side can be improved.

[0067] Combination Figure 4 and Figure 5 As shown, in some embodiments of this application, a drain outlet 213 is provided on the step surface 212 of the step portion 21. The drain outlet 213 is located inside the panel assembly 1 and also on the circumferential outer side of the inner chassis 31, so as to improve the protective effect of the housing 100 on the chassis body 2, the inner chassis assembly 3 and the panel assembly 1.

[0068] Reference Figure 3 As shown, the inner chassis 31 is mounted on the step surface 212, and the bottom wall of the inner chassis 31 can be connected and fixed to the upper wall of the step portion 21 (i.e., the wall forming the step surface 212) to achieve the connection and fixation between the inner chassis 31 and the chassis body 2, thereby fixing the inner chassis assembly 3 to the chassis body 2. The inner chassis 31 and the chassis body 2 can be connected and fixed using threaded connectors (such as screws, bolts, etc.). For example, the threaded connectors can be sequentially inserted into the inner chassis 31 and the chassis body 2 in the vertical direction (i.e., the direction in which the inner chassis 31 is mounted on the chassis body 2), thus connecting and fixing the inner chassis 31 to the chassis body 2.

[0069] It is understandable that the step surface 212 of the step portion 21 is located inside the panel assembly 1, so that the drain outlet 213 is also located inside the panel assembly 1. Water entering the step surface 212 through the outer wall 211 of the panel assembly 1 and the step surface 212 can be discharged through the drain outlet 213, thereby preventing water from stagnating in the space formed by the step surface 212, the inner chassis assembly 3 and the panel assembly 1. This prevents water entering the step surface 212 from being sucked into the arrangement space of the indoor unit through the gap between the sealing flange 321 and the panel assembly 1, which helps to improve the protection effect of the indoor unit and can prevent rainwater from stagnating for a long time and causing bacteria to grow or produce odors.

[0070] Meanwhile, by setting the drain outlet 213 on the outer circumferential side of the inner chassis 31, interference between the inner chassis 31 and the drain outlet 213 can be prevented, such as the inner chassis 31 blocking the drain outlet 213, so that water entering the step surface 212 can be discharged in time through the drain outlet 213.

[0071] Furthermore, since the sealing flange 321 and the step surface 212 are in a clearance fit, the risk of water entering the gap between the sealing flange 321 and the panel assembly 1 only exists when the water level remaining on the step surface 212 reaches the lower end of the sealing flange 321. This allows water entering through the gap between the panel assembly 1 and the outer wall 211 of the step portion 21 to flow inward first and be discharged through the drain outlet 213, thus achieving drainage protection at the chassis body 2. At the same time, a first sealing element 41 also forms a sealing protection between the sealing flange 321 and the panel, thereby further improving the protection effect on the indoor unit side.

[0072] like Figure 3 As shown, in some embodiments of this application, a reinforcing flange 14 is provided on the panel assembly 1. The reinforcing flange 14 is bent outward from the lower end of the panel assembly 1 toward the side away from the step portion 21, so as to improve the structural strength of the panel assembly 1 at the lower end by means of the reinforcing flange 14. The reinforcing flange 14 can overlap and cooperate with the wall surface of the chassis body 2 where the step portion 21 is formed in the vertical direction, so as to improve the protective effect between the panel assembly 1 and the chassis body 2 by means of the cooperation between the reinforcing flange 14 and the chassis body 2.

[0073] In some embodiments of this application, the chassis body 2 can be constructed as a frame structure consisting of multiple beam segments connected end to end.

[0074] Combination Figure 4 and Figure 5As shown, in some embodiments of this application, the panel assembly 1 includes: a first panel 11 and a second panel 12. The first panel 11 is arranged vertically and connected to the chassis body 2. One end of the first panel 11 has a first connecting rolled edge 111, and the first connecting rolled edge 111 has an outwardly open mounting groove 1113. The second panel 12 is arranged vertically and connected to the chassis body 2. One end of the second panel 12 has a second connecting rolled edge 121, and a second sealing member 42 is provided on the inner wall surface of the second panel 12.

[0075] Furthermore, the first panel 11 and the second panel 12 are connected and engaged to place at least a portion of the second connecting crimp 121 into the mounting groove 1113, and a seal is formed between the second panel 12 and the first panel 11 by the first connecting crimp 111 and the second sealing member 42.

[0076] Combination Figure 4 and Figure 5 As shown, the first panel 11 has an outwardly open mounting groove 1113 formed at the first connecting rolled edge 111. The second panel 12 can be fastened to the first panel 11 so that the second connecting rolled edge 121 extends into the mounting groove 1113 from the open end of the mounting groove 1113. The first connecting rolled edge 111 can press against the second sealing member 42 on the inner side of the second panel 12 so that the second sealing member 42 forms a sealing structure between the first panel 11 and the second panel 12, thereby ensuring the sealing effect between the first panel 11 and the second panel 12 and preventing contaminants outside the housing 100 from entering the indoor unit side through the gap at the mating point of the first panel 11 and the second panel 12.

[0077] It is understandable that, since the mounting groove 1113 at the first connecting rolled edge 111 of the first panel 11 is open to the outside, the second panel 12 can extend the second connecting rolled edge 121 into the mounting groove 1113 by snapping it inward from the outside, so that the first panel 11 and the second panel 12 are limited and engaged by the cooperation of the first connecting rolled edge 111 and the second connecting rolled edge 121.

[0078] Reference Figure 5 As shown, the first connecting rolled edge 111 includes a rolled edge body 1111, which forms an outwardly open mounting groove 1113. The mounting groove 1113 has a U-shaped cross-section. A connecting plate segment 1112 is provided at the open end of the rolled edge body 1111. The connecting plate segment 1112 extends from the rolled edge body 1111 towards the side away from the opening of the mounting groove 1113 and is disposed opposite to the second panel 12. The connecting plate segment 1112 is used to connect and cooperate with the second panel 12 to realize the connection and fixation of the first panel 11 and the second panel 12.

[0079] Furthermore, the connecting plate segment 1112 and the second panel 12 can be connected and fitted by a connector (such as screws). The connector can pass through the second panel 12 and the connecting plate segment 1112 in sequence, and connect and fix the second panel 12 and the connecting plate segment 1112.

[0080] In some embodiments of this application, the second connecting rolled edge 121 is formed with an opening facing the side wall of the rolled edge body 1111 connected to the connecting plate segment 1112, such that the opening of the second connecting rolled edge 121 faces away from the gap between the first connecting rolled edge 111 and the second connecting rolled edge 121, so that the first connecting rolled edge 111 and the second connecting rolled edge 121 form a maze structure around each other, increasing the difficulty for external contaminants of the housing 100 to enter the sealing joint between the connecting plate segment 1112 and the second panel 12.

[0081] In some embodiments of this application, the housing 100 further includes a third seal 43, which is disposed in the mounting groove 1113 and is used to form a seal between the first connecting crimp 111 and the second connecting crimp 121 to improve the sealing and protection effect at the mating point of the first connecting crimp 111 and the second connecting crimp 121.

[0082] It should be noted that the third sealing element 43 can be disposed between the bottom wall of the rolled edge body 1111 (i.e., the wall surface of the rolled edge body 1111 that is opposite to the opening of the mounting groove 1113) and the second connecting rolled edge 121, so that the second connecting rolled edge 121 can gradually press against the third sealing element 43 as it extends into the mounting groove 1113 from the outside to the inside, so as to clamp the third sealing element 43 through the first connecting rolled edge 111 and the second connecting rolled edge 121, and ensure the sealing effect between the first connecting rolled edge 111 and the second connecting rolled edge 121.

[0083] In some embodiments of this application, the second seal 42 and the third seal 43 may be configured as sealing sponges.

[0084] Combination Figure 4 and Figure 5 As shown, in some embodiments of this application, the first connecting rolled edge 111 and the second connecting rolled edge 121 enclose and form a vertically through drainage channel 101. The drainage channel 101 is arranged opposite to at least a portion of the drain outlet 213 in the vertical direction so that the water between the first connecting rolled edge 111 and the second connecting rolled edge 121 is discharged downward through the drain outlet 213 on the chassis body 2, thereby improving the sealing and protection effect at the mating point of the first panel 11 and the second panel 12.

[0085] It is understandable that the first panel 11 and the second panel 12 are both arranged vertically. Water entering the gap between the first connecting rolled edge 111 and the second connecting rolled edge 121 can adhere to the first connecting rolled edge 111 or the second connecting rolled edge 121. Under the action of gravity, the water can flow downward and flow to the drain outlet 213 to drain the water that has entered the gap between the first connecting rolled edge 111 and the second connecting rolled edge 121.

[0086] The housing 100 for HVAC equipment according to the embodiments of this application has at least the following advantages:

[0087] (1) The panel assembly 1 is connected and fitted with the outer wall 211 of the upper step 21 of the chassis body 2 to form a protective structure between the panel assembly 1 and the chassis body 2. The sealing flange 321 of the inner chassis assembly 3 and the panel assembly 1 form a sealed protective structure through the first sealing member 41. A drain outlet 213 is provided on the step surface 212 of the step 21 to drain water in time through the drain outlet 213, thereby improving the waterproof performance of the shell 100 and preventing rainwater from staying in the step 21 for a long time and causing bacteria to grow and produce odors.

[0088] (2) A sealing and protective structure is formed between the first connecting rolled edge 111 of the first panel 11 and the second panel 12 by the second sealing member 42, so as to prevent water from being sucked into the indoor unit side through the gap between the first panel 11 and the second panel 12, thereby improving the sealing and protective effect between the first panel 11 and the second panel 12. A sealing and protective structure is also formed between the first connecting rolled edge 111 and the second connecting rolled edge 121 by the third sealing member 43, so as to form a multi-layer sealing and protective structure between the first panel 11 and the second panel 12.

[0089] The HVAC equipment according to the second aspect of this application includes the housing 100 described above. The housing 100 has good sealing and protection effects at the panel assembly 1, the mating point between the panel assembly 1 and the chassis body 2, and the mating point between the panel assembly 1 and the inner chassis assembly 3, so as to prevent contaminants outside the housing 100 from entering the arrangement space of the housing 100 in the indoor unit side equipment.
